this paper examines the historical development of operations research (or) and represents different or methods (methodologies) developed during its lifetime. then, considering thomas kuhn’s paradigm model of scientific development as a basis for our work, the former and current status of or are analyzed and the future trend is discussed.
This paper applies life cycle concepts to forecast and explore trends in the publication rates of operations research (OR) methodology journal articles. The confirmatory part of this study seeks to show the accuracy of life cycles to forecast a trend for a single OR methodology. The exploratory part of this study extends the use of life cycle forecasting to a broader collection of OR methodolog...
In the past few decades, air traffic problems at major airports have been increased significantly and are expected over in the near future, which imposes a high requirement for more efficient cooperation across all airport operations. Thus, determining efficient airport operations is an important and critical problem for airports, airlines, passengers and other stakeholders. In this situation, ...
This paper presents three new methodologies for the basic operations, which aim at finding new ways of computing union (maximum) and intersection (minimum) membership values by taking into effect the entire membership values in a fuzzy set. The new methodologies are conceptually simple and easy from the application point of view and are illustrated with a variety of problems such as Cartesian p...
Demand information is an input for a great deal of operations research models. Assumed as given in many problem instances addressed in the literature, demand data are di cult to generate. In this tutorial, we provide an introduction to disaggregate demand models that are designed to capture in detail the underlying behavioral mechanisms at the foundation of the demand.

In this course, one main objective is to demonstrate the wide applicability of operations research tools to real systems. Hence, we will focus on modeling and analysis of various economic and social problems as illustrated by examples from the literature. Although we will not cover any solution technique in depth, we will introduce some new analysis tools that are typically outside the scope of...
